Epoxy alternative

[Finmore]

Could this stuff work on a plywood build? It is potable water safe, requires no mixing, can be applied without using a respirator, and is priced cheaper than 2-part epoxy. Plus, its elastic properties are very appealing:

Ames Super Elasto Barrier

the only thing that cocerns me is the mold and mildew resistance,could be toxic to the fish contact the company and post what they say

From what I read on the link that was posted

Super Elasto-Barrier is potable water compliant, and contains no toxic substances after curing. Super Elasto-Barrier is your best choice for flat roof repair.

I would venture to say that it would be fine to use. If it were not potable water compliant and contain no toxic substances then I would question it. But that dont mean to not ask the company to be sure.

as other replies being potable water compliant it should be safe but being rubber based you willhave a problem sticking your viewig window in i dont think silicone would stick fiberglass and epoxy is rely had and smelly work and expensive but if its done right its bullitproof

says it is safe for pond applications. The only thing that worries me is that if you scroll down it has tape that is supposed to help in areas prone to splitting over time such as seams, like in the corners of your tank. That says something to me, but what do I know lol. It says right there that over time it's prone to splitting.

Use the material to install the window.

I must be going blind...I didn't see anything about ponds or cracking...

Says it can be used for ponding applications in the first paragraph, and scroll down it has tape that is supposed to help keep cracking and splitting to a minimum. I might just be crazy though. Been told that a few times lol.

 

[necrocanis]

I guess to be fair it says extremely wet situations where the water is ponding.

I've been emailing several epoxy manufactures about this and there seems to be a difference between potable water safe epoxy and aquarium safe epoxy.

The basic difference right now is that when tested after curing is the AMOUNT of water diluting any residual chemicals. Most of the potable water stuff is tested at 1000 gals or more. I dont know the details and the mfgrs. are being rather difficult about it.

I know the West System Epoxies are used by a lot of folks in aquarium builds. However, if you go to their site they will tell you that people have used their products for water tank building. But they will also tell you that their product has not been approved by anyone for that purpose.

One mfrg. told me that most home aquarium builds he's heard of just use regular marine epoxy with few or no problems. That's fine but given a choice I'd rather be a little safer and go with potable safe.
